Koa vs Rails API: What are the differences?
Developers describe Koa as "Next generation web framework for node.js". Koa aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware. On the other hand, Rails API is detailed as "Rails for API only applications". Rails::API is a subset of a normal Rails application, created for applications that don't require all functionality that a complete Rails application provides. It is a bit more lightweight, and consequently a bit faster than a normal Rails application. The main example for its usage is in API applications only, where you usually don't need the entire Rails middleware stack nor template generation.
Koa and Rails API can be primarily classified as "Microframeworks (Backend)" tools.
Koa and Rails API are both open source tools. Koa with 26.6K GitHub stars and 2.42K forks on GitHub appears to be more popular than Rails API with 5.26K GitHub stars and 293 GitHub forks.
